At one point the caravan increased to 7,000 people, but many of them succumbed to exhaustion, sleep and sickness along the way and chose to stay behind in Mexican towns. Others turned back to their country of origin.

The hardest hit by these events are undoubtedly the children, unaware of the magnitude of their journey and unable to keep up with its physical requirements.

The photographs taken by journalists following the caravan have highlighted the plight of child migrants and their parents. The impact of the journey on migrant parent-child relationships has been less discussed.

Their emotionally distraught state can sometimes lead to overprotectiveness, harshness in parenting and even reversal of parent-child roles. Children in these circumstances are more likely to suffer from mental health problems.

Infections, Dehydration, Tear Gas

The caravan formed in San Pedro Sula, Honduras, on October 13, nearly seven weeks ago. The 500 migrants who have been in the caravan from the beginning have marched a total of 4,000 blistering km on their way to Tijuana.

This adds to the list of concerns their parents already have. The batons and tear gas that these migrants have faced at the United States border further adds to the stress of relocation.

Financial Strife and Marital Discord

The biggest push factors for these asylum seekers are the corruption and poverty rampant in their countries. According to the World Bank, two-thirds of the population of Honduras lived in poverty in 2016. According to the CIA World Factbook, over 30 percent of the population lived under the poverty line in El Salvador at the same time.

The signs of the migrants’ financial strife are evident. Migrant families have relied heavily on the generosity of strangers for food, shelter and transportation in the towns they have passed through. There is also the fact that people simply do not walk 4,000 km if they can travel the same distance in any other vehicle. In some cases, families have resorted to begging along the way for passage.

Gang Violence and Dissociation

Migrant families have reported fleeing their hometowns due to threats against their lives, or the lives of family members, if they did not join the local gang. Often, gangs also extort cuts of people’s already meagre livelihoods and threaten others with physical and sexual assault.

Other fallouts include dissociation (feeling cut off from reality) and lower understanding of and tolerance towards their child’s psychological distress.

As a result, children are more likely to develop emotional difficulties, learn disengagement and form similar unhelpful coping mechanisms.

Need for Social and Emotional Support

Today in Tijuana, some asylum-seeking families await to be processed by authorities while others begin to settle into life in Mexico. Their parent-child relationships will be further tested and strained under the pressure of acculturation and other post-migration stressors.

This underlines the need for social and emotional support at the end of this journey, as well as efforts to help them rehabilitate into safer areas.

Childhood is already a delicate time for growth and development, even when good enough parenting and a stable, nurturing environment is available. A grueling move to a strange and potentially hostile country obviously feels necessary for these migrant families—or they wouldn’t be on the move.

Given the life they are fleeing, an uncertain future in an idealized country eclipses certain desolation and death in their homelands.
